README states order of LngLat twice in the same way

[JeanneKahn]

In the README section describing the ground track code, it says:

// Returns points in [lng, lat] order when true, and [lng, lat] order when false.
  isLngLatFormat: true

However, the two orders are the same here ([lng, lat] and [lng, lat])
